Youp!!! That´s right. I am tired of that Hello Kitty standard horn that my ADV has. Hella twin horns are not enough for what I need. I need a horn that can move a car away from my way, and better if the driver gets scared or alarmed. If I see a dumbass using his/her phone, I can drive aside her/him and horn until s/he gets that´s a stupid habit, and pretty dangerous. I need to awake the first one in the traffic light that is texting SMS with his/her phone. I need AIR horns. Illegal, noisy, and hard to install (because of the space needed). But a couple of friends and I resolved it. Installed the air compressor near the standard horn place and wired via a Relay for security. The horns were allocated in the hollow space in front of each tank, in the same cover as the turn lights are. The relay has to be a positive switch. A long hose is needed to do the installation and that´s it. It should be hosed with unions so you don´t have to disassemble both sides to disconnect air hoses. Enjoy, as I enjoy horning people, wah ha ha ha!
